Definitions

  • the present invention relates to a device for producing hot water, particularly for hot beverage dispensing machines.
  • the dispensing machines for preparing hot beverages that are currently most widely used dispense beverages obtained by dissolving powders that are soluble in hot water, and beverages obtained by infusion or decoction, such as for example coffee.
  • Beverages produced from soluble powders instead require the use of water at temperatures below 100 °C, in order to prevent, especially in the case of freeze-drying milk powder, formation of lumps generated by the protein fraction of the powders, which over time clog the dispensing ducts.
  • temperatures that ensure optimum solubilization are from 80 to 90 °C.
  • hot beverage dispensing machines are of the single-boiler type, i.e., they generally use a single boiler to bring to the appropriate temperature the water to be used in preparing the beverages.
  • the normal operation of the boiler ensures that the temperature of the water in output is the ideal temperature for preparing the soluble products, i.e., approximately 90 °C.
  • the boiler by way of an appropriately provided control and actuation system, reaches higher temperatures in order to ensure at the outlet a temperature higher than 100 °C, which as mentioned is ideal for preparing infusions.
  • a first drawback of single-boiler dispensing machines is the long waiting time in order to bring the temperature of the water in the boiler to a value that ensures the dispensing of a good coffee or in general of a good infusion.
  • a second drawback of said single-boiler dispensers arises from the fact that soluble beverages selected directly after the dispensing of an infusion are prepared by drawing water that is in the boiler at a temperature that is higher than the one appropriate for the correct preparation of a soluble beverage.
  • dispensers have been proposed which have two boilers: one used to heat water for producing the soluble beverages (which therefore operates at 80 to 90 °C), and one intended to supply water at the temperature of 105-110 °C, for preparing infusions.
  • a first drawback of these dispensing machines is their high energy consumption with respect to single-boiler dispensing machines.
  • the aim of the present invention is to eliminate the drawbacks suffered by known types of hot beverage dispensing machine, by providing a device for producing hot water, particularly for hot beverage dispensing machines, which allows to prepare soluble beverages and infusions always in optimum operating conditions.
  • an object of the present invention is to provide a device for producing hot water, particularly for hot beverage dispensing machines, which is capable of dispensing a beverage that has a temperature in the cup that is suitable for drinking it immediately, regardless of the type of beverage previously selected.
  • Another object of the present invention is to provide a device for producing hot water, particularly for hot beverage dispensing machines, which is capable of allowing the user to choose, for the selected beverage, the temperature that he prefers, within the range of the requirements of the preparation of said beverage.
  • Another object of the invention is to provide a device for producing hot water, particularly for hot beverage dispensing machines, which allows to use a single boiler, at the same time avoiding all the disadvantages associated with conventional single-boiler dispensing machines.
  • Another object of the present invention is to provide a device for producing hot water that is highly durable, easy and inexpensive to maintain, and has a competitive production cost.
  • Another object of the invention is to provide a device for producing hot water that is constructively simple and has small dimensions.
  • Another object of the present invention is to provide a device for producing hot water, particularly for hot beverage dispensing machines, which has low energy consumption, so as to be able to meet in full the strictest standards in this regard.

  • the distribution means 12 are spaced from the boiler 2 so as to avoid heating of the metallic parts, usually made of brass, by thermal conduction. Such heating causes scale, which over time increases the load losses and makes it necessary to replace the damaged components.
  • said adjustment methods also allow to control the amount of water that arrives from the discharge duct 4 and supplies the mixing means 5.
  • the adjustment means comprise a central data processing unit CPU that is capable of receiving from a user interface, for example of a per se known type, a plurality of information data related to the beverage chosen by the user.
  • a central data processing unit CPU that is capable of receiving from a user interface, for example of a per se known type, a plurality of information data related to the beverage chosen by the user.
  • such information relates not only to the type of beverage chosen (coffee, tea, chocolate, et cetera), as already occurs for currently commercially available dispensing machines, but also the thermal condition (lukewarm, warm, hot beverage) in which the user wishes to drink the beverage.
  • the adjustment means are provided with at least one first volumetric meter VM1 for measuring precisely the quantity of cold water fed to the mixing means 5 and advantageously with a second volumetric meter VM2 that is adapted to measure the quantity of hot water that arrives from the discharge duct 4 and enters the mixing means 5.
  • both the cold water supply line 3 (which can be connected to the boiler 2) and the cold water supply duct 8 (which can be connected to the mixing means 5) are provided, along their extension, with a respective one-way valves 15; in particular, said one-way valve 15 allow the passage of water, and of fluids in general, only in one direction.
  • the cold water supply line 3 and the cold water supply duct 8 can be connected, for example by means of a valve 15 which is a two-way valve, to a single source of cold water 16, such as the water distribution mains.
  • the cold water supply duct 8 constitutes a simple branch of the line 3.
  • Operation of the device for producing hot water particularly for hot beverage dispensing machines according to the invention is as follows.
  • the user by acting on the user interface, generally constituted by a keypad, selects the type of beverage being sought.
  • the central processing unit CPU controls, by acting on the valves located at the inlets 6 and 7 of the mixing means 5, the flow of hot water and cold water that enters the mixing means 5, dosing their quantities so as to establish a temperature of the mixed water at the outlet that is suitable for preparing the selected beverage.
  • the boiler 2 operates so as to dispense, in the discharge duct 4, water at a temperature of approximately 105-110 °C, which as explained is considered the optimum temperature for preparing an infusion.
  • the mixing means 5 receive in input only the hot water that arrives from the discharge duct 4 of the boiler 2 and therefore only have the function of directing the water to the station for preparing the selected infusion.
  • the central processing unit by acting first of all on said two-way valve, causes a flow of cold water in the cold water supply duct 8.
  • the central processing unit sends a command to interrupt the flows of water of the mixing means 5.
  • a particular aspect of the present invention is the fact that it is possible to provide, in a separate sector of the keypad that constitutes the user interface, a plurality of keys that allow to select different temperature conditions at which the intended beverage can be drunk.
  • the temperature conditions that can be chosen by means of said keys are “cold”, “lukewarm”, “warm” and “hot”.
  • these temperature conditions are determined by the quantity of cold water that enters the mixing means 5.
  • the outlet 9 of the mixing means 5 can comprise a plurality of openings, each of which constitutes the inlet of a respective outlet duct that is designed to send water to a preset preparation station.
  • Another refinement of the invention is the fact that it has additional distribution means 12a, which are interposed between the channel dedicated to the preparation of an infused beverage 10 and ducts 14 leading to the infusion preparation stations (10a,10b).
  • said additional distribution means direct the hot water to the station assigned to producing the selected beverage and at the same time avoid, as already explained, heating of the electric valves used to supply the water to said stations.
